Re: Come and play with an alpha board - UK conference

I hope Debconf 12 is one of the ones you are considering. It is in Nicaragua probably early July. I'll be sure to get you the info when registration opens. Videos from Debconf 11 (Bosnia) are availalbe including the ARM bof.

Re: Power regulation

<t>Is the on-board power regulator(s) going to be switching or not? Looking at the pictures of the alpha version, I see what appears to be a 3-pin regulator and don't see an inductor, so I'm guessing non-switching.<br/> <br/> So for low-power applications we will need an external switching regulator...

Re: Plug-in Computing Cores/consolidated connector

Ethernet needs to be twisted pair, usb should be sheiled twisted pair, sound should be sheilded. You can probably use the same power lines for both usb though. looks like asking for trouble.

Re: LAMP

<t>My vhost where I run my blog, email, and usenet originally had 192MB of memory and I occasionally ran out, so I upped it to 384MB and it tends to stay around 200MB used. I use ikiwiki for the blog rather than something mysql/php based though, and I did have to tune apache to use less memory. (for...

Re: Embedding R-pi in a product

<t>A price break was not expected, and I'd plan on giving a bit more. There would be tax breaks for me if the latter could be to a US non-profit, but I understand your project is small and just starting out so has not had the time or resources to think about becoming multi-national. Maybe in a few y...

Re: PCB Etching Services

I've used dorkbotpdx for some small boards -- high quality and relitivly cheap. The two-week latancy is a bit of a pain. http://dorkbotpdx.org/wiki/pcb_order

Re: Embedding R-pi in a product

<t>Would there be any objection to using R-pi in a low production volume product? I'd consider selling 100 in the first year a success, so designing my own board doesn't make sense. I've been looking at the various existing boards, and they all are too expensive, too power hungry, or lack available ...

Re: Keyboard/Mouse less Media Center using IR Remote

If you preferer going with the microcontroler, take a look at dangerousprototypes USB IR toy. Open hardware and software. The $20 price tag could be brought down if you are willing to make thousands.

LIRC is of course already packaged for Debian.

Re: Analog I/O

<t>Many microcontrolers and some ARM chips offer on-chip analog to digital and<br/> less commonly digital to analog. This is usually an alternative to GPIO selected per-pin. Does the chip selected offer this on the pins available via the GPIO connector, or will we need to use external I2C or SPI con...

Re: Cases for the Raspberry Pi

I've already got a case for my R-pi:
http://techno-viking.com/img/P.....004854.JPG

It has a built-in power supply (13V 55A), battery backup (12V 220AH), and 5500Watt generator for when the battery gets low.

Re: Keyboard/Mouse less Media Center using IR Remote

LIRC could probably be easily adapted for this -- it normally uses the control pins on a serial port.
This would give you a trainable send and receive for IR with very little in hardware costs, and it would only use a couple of gpio pins.
